CONDENSING STEAM TURBINES
Structurally, a turbine is a single cylinder accessory with stages of active type, having a high efficiency factor, high reliability when operating at rated power, as well as modes of partial and peak load. Fresh steam of given parameters is triggered in stages of the turbine to the vacuum values at the exhaust, which determines the high utilization of its potential energy and saves fuel of the power plant. The turbine condenser is designed to provide good vacuum in the circumstances of poor cooling of the circulating water, including the circumstances when there is no large cooling pond, or when cooling towers are used, or in hot climatic conditions.
There are two types of the turbine units layout. The classical scheme with the location of the condenser under the turbine saves space of the power facility. For low-power turbines, the single-level layout of the turbine and condenser can be used, which greatly facilitates maintenance and repair of these units, but also accelerates installation as new facilities are put into operation.
